I tried following the "Windows Install" and the Quickstart, but keep getting stopped at the New Project.
I HAD an install of VS 2017 that had the template there, but did not have any of the Android tools. I eventually did a clean-install of VS2017, and now don't have the template.
I've uninstalled and fresh installed VS2017 via the installer several times. Each time I chose the Mobile Development with .Net. And each time when I pick New Project, I don't have that template:
(This was going to be a screenshot, but I can't upload an image?!??! Actually, I can upload an image, but I can't post links... wtf)
There are no pending updates under Extensions and Updates. Clicking Help -> Xamarin -> Release Notes leads to a 404 page so grr to that.
I have no idea what else I can check or try.
